Unitech's System Approach to Wine and Food Testing
31 May, 2016

Unitech is proud to distribute the ChemWell autoanalyzer worldwide to the food and wine industries. We have developed ChemWell wine analysis applications for many of our reagents.  Have a look at our analyzer and our systems approach to wine testing. 

ChemWell Autoanalyzer

ChemWell for WineTM Autoanalyzer


ChemWell is an "open" system, i.e. it can use either all Unitech reagents or your current enzymatic reagents.

ChemWell Brochure

Uniquely among chemistry analyzers, ChemWell is able to run ELISA assays (in coated micro-strips).  We currently offer  Histamine ELISA & Ochratoxin A ELISA. 


Our ChemWell analyzers have automatic custom filters permitting analysis of wine tests in addition to the typical 340nm analysis used for most enzymatic tests.  And ChemWell uses very little reagent, so you can drop your reagent costs to about 1/10 of what you currently spend.


The ChemWell 2910 autoanalyzer offers:

  • Complete enzymatic automation & Ochratoxin & other EIA's automation

  • Customer training at installation includes customized Wine Protocols

  • Washes cuvettes, Pipets, Times, Calculates & Prints out concentrations automatically

  • QC Tracking


Unitech Scientific has developed a Cost Justification worksheet that gives some structure to the process of calculating the reagent savings (7 times the tests from each reagent kit) and labor savings that your laboratory would expect by adding a ChemWell autoanalyzer. 


*Compatible with Windows 10, 7, Vista and XP.


Contact us if  you would like this worksheet, or a quote.
